Transcript for Ebola Infected Aid Workers to Be Treated in Emory Isolation Room

As that American ebola victim prepares to land on U.S. Soil we want to take you inside the plane carrying the patient out of Africa en route to Atlanta for treatment. This is called an aero biological contasystem. It can house a sick patient along with medical personnel on a modified gulf stream plane. Taking extraordinary precautions and ABC's Dr. Richard Besser who has reported extensively from the ebola hot zone is right there at the hospital in Atlanta where the victims will be treated. Rich, good morning to you. Good morning, Dan. When I worked at CDC, I was involved in the development of those special pods. They were designed to be able to transport safely a person infected with the most deadly germs. Jetting away from Liberia where ebola is deemed out of control one of two missionaries either Nancy writebol or Dr. Kent Brantly is on their way back to America today. They're being airlifted one at a time in a specially designed gulf stream jet enclosed in an isolation tent like this protecting the crew from the deadly virus. It's more than 5,000 miles from Liberia to the United States. They're going to land in a secure area Dobbins air force base here in Georgia. Then transferred to nearby Emory university hospital. One of just four top level bio containment units in the country. We run through these drills before. The process will work. Reporter: Their secure unit is similar to this at the university of Nebraska. This is a drill to show how this bio containment unit can transport a person in a tented gurney called an ice sopod. You can examine them by using these gloves. Reporter: The missionary workers will be treated in this room. Each patient will be tended by two trained nurses and four infectious disease experts all wearing full body bio suits not one inch exposed. We'll maintain the safety of this hospital as well as the general public. Reporter: One patient, Dr. Brantley talked to his family on Friday. I know he was feeling a little bit better and I'm worried about him. You know, I am, but he'll be okay regardless. And while the focus here in Atlanta is on the arrival of those patients the world's attention is on the resources and efforts that are going to be needed to stop that virus in west Africa.
